tailieunhanh - A Handbook for the Mechanical Designer

These handbooks were first published as Reactor Operator Fundamentals Manuals in 1985 for use by DOE category A reactors. The subject areas, subject matter content, and level of detail of the Reactor Operator Fundamentals Manuals were determined from several sources. DOE Category A reactor training managers determined which materials should be included, and served as a primary reference in the initial development phase. Training guidelines from the commercial nuclear power industry, results of job and task analyses, and independent input from contractors and operations-oriented personnel were all considered and included to some degree in developing the text material and learning objectives | ENGINEERING COOKBOOK A Handbook for the Mechanical Designer Second Edition Copyright 1999 This handy engineering information guide is a token of Loren Cook Company s appreciation to the many fine mechanical designers in our industry.
